Early and Late In-season Nitrogen Applications
We are evaluating the influence of early and late in-season nitrogen applications on corn growth, nitrogen uptake, and grain yield using Y-drop technology to place the nitrogen fertilizer near the corn plant.
Nitrogen Rate Influences Corn Health
In current research projects we are working on updating nitrogen fertilizer rate guidelines by evaluating corn's response to increasing nitrogen fertilizer rates throughout the state of South Dakota when nitrogen fertilizer is applied before planting and/or during the growing season.

Area(s) of ResearchMy research and extension education program is focused on determining nutrient management methods that can maintain and increase crop production while conserving and reducing inputs (water, fertilizers, chemicals, etc.) in a way that minimizes environmental impact and is profitable for farmers.
Specific research areas include:
• Determining the optimal rate and timing of fertilizer application (i.e. N, P, K, and S) for profitable crop production and optimal water quality.
• Effect of source and placement of fertilizers (N, P, and K) on crop production and air and water quality.
• Influence of cropping systems that promote soil health on adjustments needed for fertilizer rate, time, source, and placement.
• Development and use of precision agriculture technologies in crop production.
